Description
text description of the units in which the value
is expressed
the expression string for this property
if true, the expression is used to generate val-
ues for the property
contains error if the last expression evaluated
with an error
type of interpolation used at a keyframe
array containing the indices of all selected key-
frames of the Property
Description
returns value of the property evaluated at
given time
sets the static value of the property
creates a keyframe at the given time (if none
exists) for the property
creates a keyframe that is an array at the given
time (if none exists) for the property
finds the keyframe with the given index and
sets the value of the property at that keyframe
returns the index of the keyframe nearest to
the given time
returns the time at which the condition given
by the arguments occurs
returns the value of the property at the time at
which the condition given by the arguments
occurs
adds a new keyframe at the given time
removes the keyframe with the given index
true if this property can be interpolated
sets the interpolation type for the key
returns the 'in' interpolationType for the given
key
returns the 'out' interpolationType for the
given key
